Synthetic approaches for thin-film halide double perovskites [PDF]

Matter, 2021
Summary Inspired by the fascinating class of hybrid organic-inorganic halide perovskite materials, halide double perovskites have emerged as non-toxic Pb-free contenders for application as active layers in optoelectronic devices. Heterovalent substitution of Pb2+ by non-toxic metal cations yields the double-perovskite structure, which allows for ...

Doubling the Stakes: The Promise of Halide Double Perovskites

Angewandte Chemie - International Edition, 2021
AbstractWhen the stakes are doubled in a wager, a player must correctly place two consecutive bets to win, but the payout is larger. Similarly, two B sites in combination dictate the properties of A2BB′X6 (A=monocation, X=halide) double perovskites.

Small-Band-Gap Halide Double Perovskites

Angewandte Chemie - International Edition, 2018
AbstractDespite their compositional versatility, most halide double perovskites feature large band gaps. Herein, we describe a strategy for achieving small band gaps in this family of materials. The new double perovskites Cs2AgTlX6 (X=Cl (1) and Br (2)) have direct band gaps of 2.0 and 0.95 eV, respectively, which are approximately 1 eV lower than ...
